SIGNALING DEVICE.

Specification of Letters Patent. Patented Dec 31, 1918 Application filed October 4, 1915. Serial No. 53.992.

To all whom it may concern Be it known that I, VVILLIAM KAIsLING, a citizen of the United States of America, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Signaling Devices, of which the following is a specification.

My invention relates to signaling devices and has to do more particularly with signaling horns such as are commonly employed as warning signals on automobiles and the like, and is more particularly directed to the hand operated type of signalinghorn in which a vibratile member such as a diaphragm is operated by means of a toothed wheel set in motion by manual means actuated by an operator. In general the object of my invention is to provide a signaling horn of the class described embodying desirable features of construction in a simple.

and economical manner. One of the features of my invention is the provision of a signaling device that may be operated in one manner to give a shrill blast and in another manner to give a more moderate blast. Other features will be more particularly pointed out in the ensuing specification;

For a more complete understanding of my invention reference is to be had to the accompanying drawings in which like reference characters denote like parts and in which- Figure 1 is a side elevation of, my improved signaling device with the casing in section; 7

Fig.2 is .a front elevation of the de Vice withthe diaphragm removed;

Fig. 6 is a partial view of the casing'show' the fastening bracket, and

Fig. 7 is a sectional view along the line 7. 7 of Fig. 1.

device comprises a casing 1, which contains the operating parts of thev signaling horn.

A diaphragm 2 preferably constructed. of

thin sheet steel is held between a pair of ing the method ofmounting the casing to.

flexible rings 8 and 4 and clamped between the rim 5 of the casing 1 and a front plate 6 by means of the clamping screws 7. 'The said clamping screws 7 passing through suitable openings of the front plate 6, ring 4, diaphragm 2, ring 3 and the rim 5 of the casing 1. The screws 7 are of a length to permit them to have screw-threaded engagement with nuts 8 and in this manner the diaphragm 2 is securely clamped between the front plate 6 and the rim 5 of the casing 1.

A T-shaped member 9 is provided which is used as a mounting means for the operating mechanism, as will be more fully described in the ensuing specification. The member 9 is provided with an opening 10, the said opening extending the length of the member 9, and a counterbore 11 is pro cup-shaped member 30, the said ratchet'14,

and cup 30 acting as a locking means'for rotatably securing they said sleeve 12 in the opening 10 of the T-shaped member 9. The sleeve 12 has helical threads 16 cut internally of'the said sleeve. the said threads 16 run ning the length of the sleeve. The counter.

bore 11in the member 9 forms a shoulder 17 which acts as a bearing surface for the en larged portion 18 of the sleeve 12.- A toothed wheel 19 isprovided having a plurality of teeth 20, the said. wheel. being mounted looselyu'pon' the sleeve 12 between the membar, 9 and ratchet 14 which has screwthreaded engagement with. the portion 13 of thesleeve 12- and when in position upon the said sleeve the, ratchet abuts against the shoulder 25' allowing a slight clearance for the said wheel 19between the member 9 and ratchet 14, thus permitting rotation of the wheel '19 independent of the sleeve 12.

An anvil 21 is secured to the diaphragm 2 in any suitable manner. As illustrated a washer 22 is placed between the anvil 21 and the diaphragm 2 and another washer 23 is placed between the diaphragmand the upset portion 24 of the anvil 21. The anvil proper protrudes so that when the wheel 19 is rotated the teeth 20 of the said wheel en gage the anvil 21 and cause the diaphragm to vibrate to produce a warning signal.

' A pawl 26 is pivotally secured to the toothed wheel 19 by means of a pin 27, the said pawl being held in engagement with the ratchet 1 1 by means of a leaf spring 28 which has one end fastened to a pin 29 staked to the wheel 19, while the other end of the spring bears against the said pawl 26. The elongated cup-shaped member 30 has screw-threaded engagement with the portion 13 of the sleeve 12, and its upper portion is shaped in the form of a hexagonal nut 31, so as to facilitate the threading and fastening of the cup upon the sleeve 12.

A shaft S is provided which has a helical thread 32 out upon it, the said helical thread 32 and the helical thread 16 of the sleeve 12 coperating, upon actuation, to bring about the rotation of the toothed wheel 19. A pin 33 is staked inside of the cup 30 and a spring 34: is slipped over the pin 33. One end of the spring 3 1 extends up into a hollow 35 of the shaft S resting against the top of said hollow, the other end of the said spring 3 1 resting against the bottom of the cup 30. Slots 36 are cut in the shaft S and extend part way of the length of said shaft S. A sleeve 37 is provided which has two internal projections 38 (see Fig. 7), which fit into the slots 36 of the shaft S, limiting the returned movement ofthe shaft as will be hereinafter described.

The mechanism as a whole is mounted upon the casing 1 andfor the purpose of alining the parts, I provide a sleeve 39 of a size to fit in'the counterbore 11 in the memher 9. A cap 4L0isplaced over the sleeve'39 and clamping screws 41 are then extended through suitable openingsin-the cap 40 and easing 1 and have screw-threaded engagement with the member 9, thus securing the mechanism as a whole to the casing 1. If it is desired the member 9 may be so arranged as to allow for a slight move'toward or away from the diaphragm to get the proper adjustment. A large 'button 42 is stakedto the top of the shaft S in any suitable manner and is provided for manipulatingthe shaftof the signaling device. Having described the apparatus comprising my improved signaling device, I will now describe the mode of operation. I

To o erate the signaling device to give a shrill blast, a downward pressure is applied to the vbutton 42, which pressure. forces the shaft S *down against the tension of the spring 33. The helical threads 32 on the shaft S cooperate with the internal helicalthreads'a1'6 of the sleeve 12 to'bring about the rotation of the saidsleeve 12 in-the di-' rection indicated by the arrow thereon. The ratchet la-bein-g threaded to the sleeve 12 rotates and transmits power through the the said sleeve 37 medium of the pawl 26 to the toothed wheel 19 which is in engagement with a tooth of the ratchet, due to the tension of the leaf spring 28 against the said pawl. The tension of the spring 28 is such that as the ratchet rotates, the toothed wheel 19 is also rotated in the same direction and onthe completion of the downward stroke of the shaft S, the toothed wheel 19, which is of considerable weight has gained sufficient momentum to continue rotating after the sleeve 12 has stopped its rotation, the pawl 26 riding over the teeth of the ratchet. The toothed wheel 19 in rotating causes its teeth 20, out upon its periphery, to engage successively the anvil 21 mounted upon the diaphragm 2, causing the said diaphragm to vibrate and produce a clear and sharp warning note. Due to the momentum of the rotarv actuator 19, the tone is produced for a considerable time after pressure has been released from the shaft S becoming less distinct as the wheel slows .down. After the pressure is released the shaft S is returned to normal by the spring 34 and its upper movement is limited by the end of the slots 36 on the shaft S engaging the projections 38 of the sleeve 37, thus preventing the shaft from being forced out of the sleeve 37 upon rotary actuator 19 as above described. Thus in my improved device I may produce a clear, sharp and loud, warning note, when necessary, ward direction upon the shaft S, but for all ordinary purposes, by simply turning the button a clear note is emitted which serves all purposes for warning pedestrians whendriving about the limits of the city.

In Figs. 2 and 6, I illustrate more clearly the method I employ for fastening the signaling device to a mounting bracket 43. The casing 1 is provided with two openings 44:, a portion 45' of the said opening being circular inshape while the otherportion i6 is slotted.

by applying pressure in a down- The bracket is U-shapedhaving extending ears 4:? and 48 which conform with the outer clrcumference o-fthe casing, 1. The ears l7 and48 have square openings 4:9 and50 of a slze to receive the square body portion 52 of the clamping screws 53.v Nuts 5 1 have screw threaded engagement with the threaded portion 55 of the screws 53, the ends 56 of the-saidscrews being upsetso asto prevent the nuts 5d from dropping from the said clamping screws. 7

To place the signaling device upon the bracketthe heads of the .S C G' S are inserted into the openings 45 which openings are of a size to allow the heads of the screws 53 to pass through. The horn is then given a slight turn to the right (see Fig. 2), bringing the square body portion 52 of the screws 53 into the square opening 46 of the casing l, and when in this position the nuts 54 are threaded down upon the clamping screws thus holding the signaling device as a whole upon the bracket 43. To remove the device from the bracket the nuts 54 are loosened and the signaling device turned to the left until the heads of the screws 53 are in line with the openings 45 and when in this position the horn may be removed from the bracket. Holes 57 are drilled in the bracket so that the bracket may be fastened in any suitable manner.

While I have illustrated a certain arrangement of parts, I do not wish to be limited to the same as many changes and modifications may readily suggest themselves to one, therefore I wish to cover all such changes and modifications as come within the spirit and scope of the appended claims.
